Jung "AcE" Woo Seo is a South Korean Protoss player turned coach and caster for StarTale. On August 13, 2014, he announced that he was switching to Heroes of the Storm and was now retired from StarCraft II.[1]

AcE was one of the four South Korean invites to IEM World Championship, which took place in March 2011. He dominated the tournament, going 10-0 in the group stage over players such as IdrA, White-Ra and MorroW. He swept mOOnGLaDe in the semifinals to face off against Moon in the finals. AcE dropped his first sets in the tournament to him, but he ultimately took first place with a 3-2 finish. Along with the $13,000 prize and IdrA leaving Korea, AcE secured a chance to compete in the up/down matches for a spot in Code S.[2] There, he lost to his teammate Virus and remained in Code A.

In 2011, AcE qualified for Code A in the first three seasons, but was eliminated in the first round each time after falling to TOP, CoCa, and viOLet, respectively. He failed to qualify for Code A until January 2012 where he qualified for the 2012 GSL Season 1's Code A by defeating PhoeNix in the finals.

In the 2012 GSL Season 1, he beat Luvsic in the Round of 48, but lost to KeeN in Ro32.
